What happened?

The backstory:

Shortly before noon on Tuesday, July 7, the Seminole County Sheriff's Office said its deputies attempted to pull over a person suspected of drug trafficking – later identified as Wheaton – in Sanford, but he did not stop his vehicle and instead sped away. Deputies did not pursue the vehicle on the ground, citing concerns for public safety. However, SCSO's aviation unit followed the vehicle.

The sheriff's office said Wheaton was clocked at over 100 mph at times. Minutes later, Wheaton was on US 17-92 where he crashed into another vehicle, near Sunnytown Road, killing Christopher Marier and Tyler Marier.
